<p>Disclosed is a layered rubber/metal product obtained by bonding an NBR to a metal with an adhesive which comprises a phenolic novolak resin, a resol resin, an NBR, white carbon, and a vinyltrialkoxysilane coupling agent in which each alkoxy group has two or more carbon atoms. As the adhesive, use is made of a solution prepared by mixing a phenolic-resin adhesive solution with a rubber-based adhesive that is an organic-solvent solution of an NBR composition obtained by compounding an NBR with white carbon and the silane coupling agent. This layered rubber/metal product has excellent frictional resistance/wear characteristics at high temperatures. The layered product decreases little in bond strength through immersion in water or an antifreeze, and can be effectively prevented from suffering peeling or the like caused by the immersion.</p> |
